VAPOR-LAM P.

SPECIFICATION forming part of Letters Patent No. 735,548, dated August 4,-1903.

Application filed May 13, 1902.

city, in the county of New York and State of New York, have invented certain new and useful Improvements in Vapor-Lamps, of which the following is a specification.

This invention relates to gas or vaporlamps;

and it consists substantially in the improve ments hereinafter more particularly. de-' scribed.

The invention has reference more especiallyto that class of gas or vapor lamps in which a suitable hydrocarbon oil is generated into vapor, which is mixed with air and consumed at one or more burners for illuminating purposes, and also in which a continuouslylighted auxiliary burner or pilot is located sufficiently within the region of the main burner or burners to cause'the latter to become ignited or relighted each time the gas or vapor is caused to issue therefrom on proper manipulation of a suitable cook or valve for the purpose. i

The present invention has for its object to so construct and organize the vapor-tube andauxiliary burner as to yield. good results in practice, and whereby the gas or oil-vapor is superheated at a point-immediately in advance of the exit or outlet therefor to the mixing-chamber.

A still further object of the invention is to provide means whereby the pressure of the supply of gas or oil -vapor to the auxiliary burner may be increased or diminished or.

controlled at will, and also to provide means whereby the outlet for the gas or oil-vapor to the mixing-chamber may also-be controlled either simultaneously with the extinguishment of the main burner or burners or independently thereof.

A still further object is to simplify the construction and operation of the lamp and to eheapen the cost of manufacture thereof as compared 'withmany former constructions heretofore devised with similar ends in view. The above and additional objects I attain by means substantially such as I have illustrated in the accompanying drawings, in

which- Figure 1 is a side elevation, partially broken Serial No. 107,061. (No model.)

' away and partly in vertical section, of a gas or vapor lamp embodying my improvements; and Fig. 2 is an enlarged vertical sectional View showing the construction and organization of certain parts or elements more clearly. Fig. 3 is a side view in detail of the main burners and vapor tube or generator; and Fig. 4 is an enlarged detail View, in part section, showing more clearly the construction and organization of the mixing-chamber, the shut-0E valve for the gas or air to the main burners, and the auxiliary burner and pressure-regulating devices therefor. Fig. 5 is a a part-sectional detail view, on a reduced scale, showing a modification of the means for operating the needle-valve of the generator-tube and the shut-off valve of the gas or vapor supply to the main burner or burners.

Specific reference being had to the accompanying drawings by the designating charac ters marked thereon, A represents an ordinary lamp-globe of glass, to the top of which is suitably mounted a metallic reflector 13, provided with a central opening a, which is surrounded by a flange b, to which is fitted and detachably secured the lower end of a vertical or upright metal cylinder or chim ney G, the upper end of which is open, and extending across the cylinder at this end is a transverse curved member 0, formed or promain burners D D, suitably connected together, and communicating with which at a suitable intermediate point of the connection between them is a branch pipe or tube i from a mixing-chamber E for supplying said burners with gas or vapor, said branch or supply pipe being provided with a valvechamber 70, directly communicating with the said mixing-chamber, as shownpThe mixing-chamber extends upwardly in the cylinder 0 for a suitable height, and being arched plan view of the main burners; and Fig. 6 isor bent at l and returned downwardly at m such return portion is in communication with a conduit 11 leading therefrom substantially at right angles and passing through an opening therefor in the adjacent side of said cylinder, the outer end of said conduit being provided with a number of openings or perforations n for the admission or ingress of airto the mixing-chamber. Enteringthe said mixing-chamber E, preferably in line with the said return portion 171 thereof, is the upper end of a vapor tube orgenerator G, which passes upwardly through an opening 0 therefor intermediate the main burners D D and extends intermediate of and parallel with the incandescent mantles p p, with which the said main burners are provided. When these burners are lighted, the heat of the mantles is imparted to the vapor tube or generator, and thus is the vaporization of the oil effected and maintained after first starting the same by the'application of a torch or other flame to the tube or generator. The said vapor tube or generator is provided in one side thereof with an oil-inlet q, to which is attached the end of an oil-supply tube g, which may be led up and out through the top of thelamp to any suitable oil-supply, and said vapor tube or generator is form ed with an internal thread a at the lower end thereof, where it is screwed onto a threaded central projection 3, formed on a plug or guide H, on which is fitted to operate a partially-rotatable sleeve H for actuating the valves of the lamp in the manner hereinafter explained, said plug or guide being formed with a central opening 25, extending all the way through the same. The said central projection s of the said plug or guide is also tapped internally at u for the reception of the externallythreaded end it of an inner tube G, which constitutes a guide for a needle-valve G the upper end of which is provided with a needle-point 9 which works in and out through a vapor exit or outlet port 9 formed centrally of a cap g, which screws upon the upper end of the vapor tube or generator, as shown. The upper end of the inner tube G is contracted at 9 so as not to obstruct the passage of oil-vapor to the said exitor outlet port 9 and the said cap 9 is preferably fiattened at g to receive a wrench for tightly screwing the cap in place or for unscrewing the same. The said operating-sleeve H is partly open at the sides for the lower portion thereof, and at its lower end it is provided with a key g which is grasped by the fingers Wheneverit is desired to turn the sleeve to operate the valves of the lamp. The upper end of said sleeve is provided with a flange 1, formed or provided with a groove 2, in which is received a portion of a bend or branch 3 of the main-valve rod 4, to be present-ly described, and passing through a suitable threaded opening therefor in one side of the lower portion of the said sleeve H is a set-screw, which bears against the lower part of the needle-valve G and it may be here stated that said needle-valve works through a packing 5, held in place in a hollow externally-threaded projection 6 on the lower end of plug or guide II by means of a gland 7, which is tightened up by means of a cap 8, screwing onto such projection. By this arrangement any oil which may by any possibility find its wayinto the inner tube around the needle-valve will be caught and absorbed by such packing and prevented from dripping from the lamp. The vapor tube or generator is held in position between two projections 9 and 10, pendent from the under side of the burners D D, by means of a setscrew 11, working in a threaded opening in said projection 10 and pressing the said tube tightly against the said projection 9, and in this way it will be seen that the parts are securely united together for conjoint operation. The said rod 4 passes upwardly through a packing 12 and stuffing-box and gland 13,10- cated at an opening in the lower side of the bend in the gas-supply pipe 1;, leading to the main burners, and at its upper part the rod is guided by a spider thereon working in the tube. Said rod is provided at its upper end with a main valve 15, which closes against the seat 16, formed at the point of communication of the mixing-chamber E with the valve-chamber k, and it should be also explained that the operating-sleeve II is formed in one side, near the upper end thereof, with an inclined slot, through which projects a pin or projection 17 on the side of the inner plug orguide H. It is thus apparent that by turning said sleeve in one direction the needle-point of the needle-valve will be projected through the vapor-exit port. in the upper end of the vapor tube or generator, while by turning said sleeve in the reverse direction the said needle valve and point will be retracted or withdrawn. Simultaneously with these operations of the said needle-valve the main valve will also be operated to close and open communication between the mixing-chamber and valve-chamber, as is evident from the construction and organization of elements already described.

Surrounding the upper part of the vapor tube or generator immediately beneath the adjacent portion of the mixing-chamberis an auxiliary or pilot burner, comprising an annular ring or flange 20 of increased diameter over said vapor tube or generator and combined with an inner cone N, the base or enlarged end of which is fitted at 21 to the lower edge of said ring or flange 20, while the smaller or contracted end thereof fits within the opening of the mixing-chamber through which the upper portion of the vapor-tube passes and closely fits said tube, as shown in Figs. 1 and 2. Said cone is formed all around with perforations or openings 22, and communicating with the space 23 intermediate the cone and the ring or flange 20 is one end of ashort tube 25, the other end of which communicates with the inner side of the mixing-chamber and is conical at 26 to form a seat for the conical end 27 of a regulatordevice or screw-valve 30, which works in an internally-threaded boss or bearing 31 therefor formed on the outer side ofthe said mixingchamber at that point. screw also extends through an opening in the side of the cylinder on the globe, so as to be readily accessible whenever it is desired to adjust the same for regulating the pressure at which gas or vapor is admitted to the auxiliary burner from the mixing-chamber.

As shown in Fig. 6, I employ substantially the same operating device or sleeve for the needle-valve; but instead of operating the main valve simultaneously therewith I disconnect the main-valve rod 40 from the said sleeve and extend the length of said rod through a lower bearing 41 therefor, so as to bring the same in convenient reach of the operator for independently operating the main valve, if desired. In this example or modification also I prefer to use some means for holding the main valve to its closed position against the pressure exerted by the gas or mixed oil-vapor and air, and in the present instance I provide for this purpose a spring-arm 42 on the valve-rod, which is formed at its upper end into a hook 43, to engage or take into notches etet inan upper bearing 45 for said rod pendent from the under side of the adjacent portion of the mixing-chamber. This or some equivalent construction may be resorted to in some instances, if desired; but it will be understood that in practice I prefer the general construction and embodiment of my invention first described with reference to Figs. 1 to 5 of the drawin gs.
